In addition to a DirectX 9 code path, Dirt 2 also utilizes a number of DirectX 11 features, like hardware tessellated dynamic water, animated crowd, dynamic cloth effects, in addition to DirectCompute 11-accelerated high definition ambient occlusion (HADO), full floating point high dynamic range (HDR) lighting, and full screen resolution post processing. Performance-wise DX11 didn't take its toll as much as you'd expect this early on in its adoption cycle."
